Dear Sanchita,
B Jacob has given you some excellent food for thought. I will raise a few questions before making comments. May we know who is the target audience: school teachers or adult educators? What is the objective of the presentation and how long will a session last? What should be the outcome for the participants that take active part in a session?
When I started as a lecturer in a college, I was told that a good tutor would state what would be covered in the session at the outset, then cover the topic, and, finally, summarise what was covered. As I gained experience and some knowledge of Effective Teaching (by reading Wilbert McKeachie's Teaching Tips), I started to state what the active participants would gain or could do by attending the session, then state what I intended to state, and ask the participants to summarise what was covered/what they learnt. Please see
University of Virginia Teaching Resource Center <link updated to site home> ( Search On Cite | Search On Google ) for a review of that book.
I hope these tips make sense and will be of some use to you. Thank you for attaching the presentation and soliciting comments.
